AbstractThe release of Am-241 during corrosion of the radioactive waste glass, JSS-A, has been studied in the presence of corrosion products and/or uncom-pacted bentonite. The corrosion behaviour of Am-241 has been analyzed using gamma spectrometry. Adsorption of Am-241 on bentonite is observed in all cases. The contents of Am-241 in centrifuged leachates are in most cases less than 1/100 of total values. The normalized elemental mass loss of Am increases initially with corrosion time, and the values in the presence of bentonite and corrosion products are larger than those in the presence of bentonite alone. This tendency is in agreement with results previously found for other elements. The release of Am is low, only about 10–20 % of the corresponding total mass loss.

In this study, a waste of biorefinery—lignin—is investigated as an anticorrosion coating on stainless steel. Corrosion behavior of two lignin types (hardwood beech and softwood spruce) was studied by electrochemical measurements (linear sweep voltammetry, open circuit potential, potentiostatic polarization, cyclic potentiodynamic polarization, and electrochemical impedance measurements) during exposure to simulated body fluid (SBF) or phosphate buffer (PBS). Results from linear sweep voltammetry of lignin-coated samples, in particular, demonstrated a reduction in corrosion current density between 1 and 3 orders of magnitude cf. blank stainless steel. Furthermore, results from cross cut adhesion tests on lignin-coated samples demonstrated that the best possible adhesion (grade 0) of ISO 2409 standard was achieved for the investigated novel coatings. Such findings suggest that lignin materials could transform the field of organic coatings towards more sustainable alternatives by replacing non-renewable polymer coatings.

In this paper, the corrosion behavior was researched which was happen on the 304,321,316Lect. stainless steel materials in the analogue situation of calcining gas atmosphere of ammonium paramolybdate.The oxidized etch which happened on the sample’s surface, phase constituent and element content of the fracture surface, was analyzed by the means of SEM、XRD.The results showed that the phases of Fe2(MoO4)3,MoO3,MoO2.5(OH)0.5,Cr2O3,Cr2Ti5O13, Fe2O3,Fe3O4 ect. are contained on the surfaces of the 304,316L, 321 samples which are calcined. There is an inside oxidized corrosion layer in 304 316L. The oxidizing film is damaged and the oxygen penetrates into the base to form an oxidized layer. A thin and compact oxidation film was formed between 321 corrosion layer and the alloy interface, which have prevented the base from further corrosion, under this experiment conditions, this steel belonged to the inoxidizability materials. The coating deficiency of 321 steel is shallow; the particles of oxidate is thin and without inner corrosion; the weight gain rate of oxidized etch is slow (average rate 5.2×10-2mg/ (cm2•h)), the weight gain is less and corrosion resistance is fine.
